The TVME8240 will perform write cycles to the IP ID space.
Any access to the IP INT space will assert the IP INTSEL# signal on the selected IP slot. The
TVME8240 will perform write cycles to the IP INT space.
The user should perform IP INT space read cycles on the desired IP slot to generate an IP
INTSEL# cycle and read the interrupt vector. For this read cycle the address must reflect if the
IP INTSEL# cycle is for IP INT0# or for IP INT1#.
